FILLING-CHANGING ME CHANISM FOR 'LOOMS.

ePEUIFIGATION forming part of Letters Patent No. 658,324, datedSeptember 18, 1900.

Application filed June 28, 1900. Serial No. 21,264; (No model.)

To all whom it may concern" Be it known that I, EDWARD S. STIMPSON, acitizen of the United States, and a resident of Hopedale, county ofWorcester, State of Massachusetts, have invented an Improvement inFilling-Changing Mechanism for Looms, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on the drawings rep to resenting likeparts.

In United States Patent No. 627,803, dated June 27, 1899, an automaticmechanism is shown for automatically changing the filling in a loom, thefilling-carriers being mounted in a feeder which is moved intermittinglyby or through a strong spring to bring the fillingcarriers singly intooperative position for transfer, the lay operating to set the spring.

My present invention relates to fillingzo changing mechanism of thisgeneral type; but herein the feeder-actuating spring is set by orthrough the operation of the transferrer, and I have provided a novelconstruction and arrangementof the parts foractuating the feeder. I havealso provided-means for positively efiecting engagement of the actuatingpawl with a cooperating ratchet attached to the feeder when said pawl isretracted.

Figure l is a front elevation of a portion of a loom provided withfilling-changin g mechanism embodying my invention; and Fig. 2 is atransverse sectional view thereof on the line a; at, Fig. 1, lookingtoward the right.

3 5 The loom-frame A, lay A breast-beam A bunter C the filling-changingmechanism, comprising, essentially, connected disks a a to support thefilling-carriers I), (see dotted lines, Fig. 1,) the stud a fixed on thestand a 40 on which the disks rotate, and the ratchet wheel or teeth a",attached to the hub of the disk or, and the transferrer f, may be andare substantially as shown in the patent referred to, the disksconstituting a filling-feeder,

as it will be hereinafter termed.

The foot of the stand a is shown as provided with a horizontal hub orbearing a through which is extended a stud f, projecting beyond the hubat each end and held from set-screw 2.

movement therein by-suitable means, as a The transferrer ismounted torock on the stud between the disks, and a spring 3, surrounding thestud, is attached at one end to the transferrer and at its otherend to acap 3, suitably pinned or otherwise secured to the stud, the springtending to lift the transferrer into'normal position, as shown in thedrawings. The controlling mechanism for the transferrer, including thedog m", governed as to its position by the rock-shaft d and interveningconnections, may be and is substantially as shown in United StatesPatent No. 628,228, dated July at, 1899 At the other end of the stud f Ihave mounted the hub h of a pawl-carrier it, having pivotally connectedtherewith, as; at 4:, Fig. 2, an upturned pawl h adapted to cooperatewith the ratchet a, one end of the strong spring S being connected withthe pawl-carrier, the other end of the spring being secured to a cap 6,fastened on the stud, the tendency of the spring being to rock thepawl-carrier in the direction of the arrow 25, Fig. 2.

. The spring Sis the feeder-actuating spring and it is wound or set byretraction of the pawl-carrier in the direction opposite to the arrow25.

The hub it has secured to or forming part of it alongitudinally-extended ear k which projects over an oppositely-extendedlug f secured to the hub of the transferrer, as clearly shown in Fig. 1.

When the transferrer is moved in a downward direction to transfer thefilling-carrier then in operative position from the feeder to theshuttle, the lug f will be lifted and it acting upon the ear 77,depresses or retracts the pawlcarrier h, winding or setting thefeeder-actuating spring S and moving the pawl h into position to engagea fresh tooth go on the ratchet a When the transferrer returns to itsnormal position, the spring S 0perates through the pawl-carrier and pawlto effect a partial rotation of the feeder sufficient to bring the nextfilling-carrier into operative position, as in the patents hereinbeforereferred to.

It will'be noted that the pawl-carrier is in this invention mountedadjacent the transferrer, the fulcra of the transferrer and pawlcarrierbeing in alinement.

The mechanism is very simple, strong, and durable, and thefeeder-actuating spring is mounted exteriorly to the feeder, Where itmay be easily reached for repairs or adjustment. In order to insure theengagement of the pawl with the ratchet when the pawl-carrier isretracted, I have provided a cam to act thereupon, said cam being hereinshown as a lug m mounted on the inner face of the stand a and adapted toengage a shoulder h on the inner side of the pawl, the cam by suchengagement positively moving the pawl toward and into operative positionrelative to the ratchet. The detent-pawl (Z of suitable construction isprovided to cooperate with the ratchet and prevent retrograde movementof the filling-feeder.

Having fully described my invention, what I claimas new, and desire tosecure by Letters Patent, is

1. A movable filling-feeder to hold a series of filling-carriers, meansto intermittingly actuate the feeder, including a pawl, and a cam toengage the pawl when retracted and positively move it into operativeposition.

2. A movable filling-feeder to hold a series of fillingcarriers, anattached ratchet, means, including a pawl and a pawl-carrier, to intermittingly actuate the feeder, and a cam to engage the pawl uponretractive movement of the pawl-carrier and positively effect eugagementof the pawl with the ratchet.

3. A rotatable filling-feeder, an attached ratchet, a pawl-carrierfnlcrumed eccentric to the axis of the feeder and having a pawl tocooperate with the ratchet, to intermittingly rotate the feeder, anactuating-spring for the latter, set by retraction of the pawlcarrier, atransferrer, and means controlled by operation thereof to retract thepawl-carr1er.

4. A rotatable filling-feeder, an attached ratchet, a cooperatingspring-actuated pawl, to efifect intermitting rotation of the feeder, atransferrer, means contrplled by its operation to retract the pawl, anda cam to engage the pawl when retracted and positively eifect itscooperation with the ratchet.

5. A rotatable filling-feeder, an attached ratchet, a cooperating pawl,its pawl-carrier, a transferrer, the fulcra of said pawl-carrier andtransferrer being in alinement with each other, a feeder-actuatingspring set by retraction of the pawl-carrier, and means controlled byoperation of the transferrer to retract the pawl-carrier.

6. A rotatable filling-feeder, an attached ratchet, a cooperating pawl,its pawl-carrier, a transferrer, a fixed fulcrum -stud upon which saidtransferrer and pawl-carrier are mounted to rock, a feeder-actuatingspring set by retraction of the pawl-carrier, and connections betweenthe latter and the transferrer, to retract the pawl-carrier when thetransferrer is operated. I

7. A rotatable filling-feeder, an attached ratchet, a spring-actuatedpawl-carrier, a pawl pivotally mounted thereon to cooperate with theratchet, means to retract the pawlcarrier, and a fixed cam in the pathof the pawl when retracted, to positively elfect its codperation withthe ratchet.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD S. STIMPSON.
